    Study Notes

    Instruction Set Architecture (ISA)

    • Definition: A specification of how a computer's central processing unit (CPU) interacts with computer hardware and memory.
    • Key characteristics: Defines the machine code, instruction formats, operands, addressing modes, and registers.
    • Types: RISC (Reduced Instruction Set Computing) and CISC (Complex Instruction Set Computing).
    • Impact: ISA affects performance, cost, and how programs are written for a particular processor

    Assembly Language

    • Definition: A low-level programming language that uses mnemonic instructions to directly control the computer hardware.
    • Relationship to Machine Code: Assembly language is a symbolic representation of machine code—the assembler translates assembly instructions into machine code.
    • Syntax: Different assembly languages use different syntax rules; these depend on the ISA.
    • Key elements: Includes instructions, data declarations, labels, etc.

    Assembly Programming Components

    • Instructions: Represent operations the CPU can perform (e.g., arithmetic, logical, data movement).
    • Data types: Define the kind of data assembly programs use (e.g., integers, characters).
    • Registers: Special storage locations inside the CPU; used for holding temporary data during processing.
    • Addressing modes: Methods of specifying operands (data locations) in memory or registers (e.g., immediate, direct, register, indirect).
    • Memory: Programs and data are stored in memory locations.
    • Control flow: Instructions determine the sequence in which the computer executes other instructions (e.g., conditional, unconditional jumps).
    • Subroutines: Blocks of instructions that perform specific tasks; can be reused.
